Gamed it a week and a half ago with the new gears, and used it at a team practice last weekend.
So far the gears are performing beautifully, but with that solved I discovered a couple other things.
1. A good reminder to apply blue Locktight to all screws in the gearbox... Forgot to lock tight the screw on my spring guide in place so that was doing a nice dance inside my spring/piston lol. Fortunately it stayed inside the coils of the spring.
2. Some of my bushings have started to slip and actually spin the the gearbox housing, it's happening on three of them, two on one side, one on the other. Planning on removing the bushings and applying a little JB weld to the walls of the bushings, then inserting back in place and re-shimming. These bushings should never fail so welding them in place isn't too much of a concern. If they ever did a hammer and punch should get it out easily enough anyway.
